Definitions
- the field of the invention is metering and dispensing devices for a powder or granular material. More particularly, it relates to a powder dispensing closure which is connected to a container and can dispense accurate amounts of the powder into a liquid or container.
- Dispensers of the type concerned with in this invention are disclosed in U.S. Patents Nos. 4,032,050 and No. 5,469,992. Both of these dispensers disclose a rotatable metering disk (80 and 20, respectively) for materials to be dispensed. There are problems with a rotatable measuring piece and stationary feed pieces. These cannot effect a desired internal stirring action of the container contents. Without this action, a significant amount of powder can be left in the container and not deposited into the measuring chamber.
- the prior art does not provide a metering and dispensing closure which is connectable to a container and affords suitable sealing for powder materials which are hygroscopic.
- the feed-rate varies over at least a 3:1 range and sometimes more due to the amount of powder remaining in the container, any bridging that may occur due to solidification near the screen, water pressure, spray pattern variation, water temperature and batch to batch variations.
- these systems typically require a concentration feedback control subsystem to compensate for their variable feed-rates.
- concentration feedback control used in dishwashing applications.
- "spray/screen" powder dispensing systems normally can not be used in applications where a repeatable dose is required. This invention avoids this limitation by providing a precise and consistent metered dose based on a volumetric measurement.
- the "spray/screen" dispensers work only with a limited range of powders and formulations. Detergents, the most commonly fed powders, are limited to formulations that will not create excess exothermic heat if the spray should penetrate into the powder. This has typically meant that the caustic (typically NAOH or KOH) level needs to be kept below about 40% to prevent the possibility of steam generation within the container which can be a safety issue.
- the metering and dispensing closure of this invention would remove this limitation and allow more powerful detergent powders to be formulated with perhaps up to 70% caustic concentrations for soft- water dishwasher applications. This would represent a 40% to 50% increase in "power" in a single container.
- the shortcomings of the prior art are overcome by the metering and dispensing closure for a container of this invention which includes a container cap member attachable to the container.
- the container cap member has a first side adapted to be mounted facing an inside of the container and a second side adapted to be mounted facing an outside of the container.
- a rotor is mounted on each side of the cap to selectively open and close an aperture in the cap member.
- a measuring chamber is positioned in the container cap member.
- a first rotatable disk member having at least one passage which is mounted on the first side of the container cap member.
- second rotatable disk member having a passage therein which is mounted on the second side of the container cap member.
- first and second rotatable disk members are connected to each other.
- the second rotatable disk member includes a drive shaft engagement portion.
- the second rotatable disk member includes a gear for engagement by a complementary gear of a drive gear.
- the cap member includes threads for attachment to complementary threads of the container.
- a powder dispensing apparatus which includes a container cap member attachable to the container, the container cap member having a first side adapted to be mounted facing an inside of the container and a second side adapted to be mounted facing an outside of the container.
- a measuring chamber positioned in the container cap member.
- a second rotatable disk member has a passage therein with the second rotatable disk member mounted on the second side of the container cap member, the first and second rotatable disk members connected to each other with the second rotatable disk member including a drive shaft engagement portion.
- Some embodiments of the invention are directed to a dispensing closure for a container.
- the dispensing closure comprising a cap adapted to be received on the container and a first and second movable member coupled to the cap.
- the cap has an inside face, an outside face, and an aperture extending from the inside face to the outside face through the cap to allow materials within the container to be dispensed.
- the first movable member is positioned adjacent the inside face of the cap to selectively block the aperture in the cap.
- the first movable member is movable between a first position in which the aperture is blocked and a second position in which the aperture is not blocked.
- the second movable member positioned adjacent the outside face of the cap to selectively block the aperture in the cap.
- the second moveable member is movable between a first position in which the aperture is blocked and a second position in which the aperture is not blocked. Movement of the first moveable member and the second moveable member is sequenced such that at least one of the moveable members is always blocking the aperture.
- a plurality of resilient fingers are coupled to the first movable member and extend from the first movable member toward the cap.
- the fingers are movable with the first movable member between a position in which the fingers are not aligned with the aperture and a position in which the fingers are aligned with the aperture.
- the resilient fingers extend into the aperture of the cap when the fingers are in the aligned position.
- the ringers are aligned with the aperture in the cap when the first movable member is in a position that blocks the aperture and the second movable member is in a position in which the aperture is not blocked.
- the fingers when the fingers are not aligned with the aperture in the cap, the fingers contact the cap and are biased by cap towards a bent over position, and when the fingers are aligned with the aperture in the cap, the fingers resiliently return to a substantially unbiased position and extend into aperture.
- the fingers are positioned within a recessed portion of the first movable member, the recessed portion extending away from the cap.
- the movable members can be rotors or disks that rotate between the first and second position. Further, depending upon the configuration of the moveable members can have a passage defined in them, wherein rotation of the first and second movable members selectively and sequentially place the first and second passages in communication with the aperture. As such, the first passage can be rotatably offset relative to the second passage.
- the second movable member comprises an edge that contacts and passes over the aperture in the cap when the second movable member moves from the second position back to the first position.
- the edge comprises a generally angled surface terminating at a point defining an acute angle. This edge can be used to scrape or otherwise remove cake, stuck, or otherwise encrusted materials from the cap.
- the generally angled surface of the edge includes a concave portion.

- the metering and dispensing closure generally 10 is shown in conjunction with a container 12 supported in a dispenser assembly or receptacle 14 for housing the closure 10.
- a water intake conduit 16 controlled by solenoid valve 18 is utilized to introduce water into the dispenser assembly or receptacle 14.
- a water solution outlet conduit 20 is also in communication with the dispenser assembly or receptacle 14.
- a drive member 22 drives a drive shaft 24, the drive shaft being journalled in the collar 26 with a seal 28.
- the metering and dispensing closure generally 10 is composed of three basic components. There is a cap member 30 with an upstanding wall 31 and internal threads 32 for engaging complementary threads on the container 12. There is also a rotatable disk 36 with a raised peripheral wall 37 as well as a cutaway portion 38. Rotatable disk 36 is seated inside the cap member 30. The third component is a rotatable disk 43 with a raised peripheral wall 46 and a stub shaft 48 with projections 49. These fit through an opening 34 in the cap member 30 in a manner that the projections 49 engage slots 41 in the rotatable disk 36. Rotatable disks 36 and 43 are rotated by the shaft 24 connected to the stub shaft 48.
- metering and dispensing closures or embodiments 1OA, 1OB, 1OC and 1OD shown in FIGURES 6, 7, 9, and 11, respectively, employ some of the same basic components as previously described for embodiment 10, except they have an A, B 5 C or D suffix.
- Embodiment 1OA illustrates two dispensing closures for the container 12A as well as two drive motors 6OA for the drive shafts 24A.
- the drive shafts 24A rotate the rotatable disk 43 A as well as an internal rotatable disk 36A not shown.
- Embodiment 1OB shown in FIGURES 7 and 8 differs from that shown for 10 in that it has a different drive mechanism for rotating rotatable disks 43B and 36B. This is accomplished by the motor 62B and the drive gear 63B which engages the ring gear 64B on the rotatable disk 43B. Rotation of disk 36B is effected by the stub shaft 48B connected to rotatable disks 43B and 36B. Another difference is the location of the water outlet conduit 2OB directly beneath the metering and dispensing closure 1OB. The interaction of the previously described components is seen in FIGURE 8.
- FIGURE 9 1 OC embodiment is similar to that of the 1 OB embodiment shown in FIGURE 7, but includes a motor 62C connected to worm drive gear 63C for driving the ring gear 64C on the rotatable disk 43C.
- Stub shaft 48B is interconnected with disks 43C and 36C to provide rotation thereof. The positioning of the rotatable disks 36C and 43C with respect to the cap member 30C is illustrated in FIGURE 10.
- the embodiment 1OD shown in FIGURE 11 differs from the embodiments shown in FIGURES 6, 7 and 9 in that yet another means for rotating the disks 43D and 36D is illustrated.
- a motor 6OD drives the drive shaft 7 ID having the sprocket 74D for engaging a chain 75D which in turn drives the sprocket 78D on the drive shaft 24D.
- Drive shaft 24D effects rotation of stub shaft 48D and accordingly disks 43D and 36D.
- FIGURES 1-5 A better understanding of the metering and dispensing device shown in FIGURES 1-5 will be had by a description of its operation.
- a container 12 with a powdered material is supported in the receptacle 14. Water will be introduced into it through the water intake conduit 16.
- the metering and dispensing closure 10 is attached to the container 12 with the cap member 30, and rotatable disks 36 and 43 shown in the position in FIGURES 3 and 3A.
- metering and dispensing closures 1OA, 1OB, 1OC and 1OD are substantially the same as described for metering and dispensing closure 1OA.
- the differences are in the use of different drive mechanisms, such as shown by the motors 6OA, 62B, 66C and 7OD with the described associated drive mechanisms.
- An important feature of this embodiment is in the stationary position of the cap member 30 in conjunction with the rotation of the rotatable disks 36 and 43. This feature provides the advantage of accurate depositing of powder material into the measuring opening 33. This is effected by the rotation of the disk 36 which causes a stirring of the powder inside the container 12 and consistent depositing of the powder material into the measuring opening 33. Another advantage in having the cap member 30 remain stationary with respect to disks 36 and 43 is that it can be manufactured more easily.
- the dispensing closure of this invention has been described in conjunction with particular configurations of receptacles. It should be understood that any type of receptacle can operate in conjunction with this dispensing closure. They do not necessary have to have a receptacle that contains water. For example, they could be utilized in a receptacle and supported therein where the powder material would drop into another container having a liquid predisposed therein. Neither is it necessary that the dispensing closure be employed in conjunction with a receptacle employed with water. Other liquids such as water- miscible and immiscible solvents including water and ether could be employed.
- cap member 30 and disks 36 and 43 The preferred material for manufacturing cap member 30 and disks 36 and 43 is polypropylene. However, other chemical resistant resinous plastic materials can be employed such as polyethylene or Teflon®. If desired, a lubricant can be added to the plastic materials.
- FIGURES 13-30 additional embodiments of the dispensing assembly 14 and the metering and dispensing closure 10 are shown.
- the dispensing assembly 14 of this embodiment has many features in common with the embodiments discussed above. Accordingly, such features will be given a common number.
- the dispensing closure 10 also has similar features to the dispensing closures 10 discussed above and will follow the numbering scheme discussed above.
- a dispensing assembly 14' is shown mated to a container 12.' Although it is not illustrated in this figure, a closure 10 embodying aspects of the invention is attached to the container. With reference to FIGURES 18- 22 is can be seen that the dispensing assembly 14' includes a cradle 55' adapted to receive the closure 10 and a portion of the container 12. The dispensing assembly 14' also includes a water intake conduit 16' controlled by a valve 18' to introduce water into the receptacle 14', a funnel assembly 57' to receive dispensed chemicals and water, and a water solution outlet conduit 20' in communication with the funnel assembly 57'. The dispensing assembly 14' also includes a drive member 22' that drives the funnel in a rotary motion, which in return drives the closure 10' between dispensing and non-dispensing positions.
- water inlet conduit 16' has a first portion 16A' and a second portion 16B' separated by an air gap 17'.
- the air gap 17' serves as a backflow prevention device.
- the water flows toward the funnel assembly 57'.
- the second portion 16B' has a channel-like configuration. Once the water leaves the second portion 16B' of the water inlet conduit 16', the water then flows through the funnel assembly 57' to flush dispensed chemicals out of the funnel assembly 57'.
- the funnel assembly 57' has a unique structure. Specifically, as best illustrated in FIGURES 22 and 23, the funnel assembly 57' is provided with a means for rotating. More specifically, the drive member 22' provides power to the funnel assembly 57' to drive the funnel assembly 57' in a rotary motion.
- the rotary motion of the funnel assembly 57' serves two purposes in this embodiment. First, the rotary motion allows the water to flush the entire funnel assembly 57' and prevent any caking or other deposits from remaining in the funnel 57'. Additionally, the rotary motion allows the funnel assembly 57 to be used to drive the closure 10' between dispensing and non-dispensing positions.
- the drive member 22' helps to avoid some potential problems that may be seen in the first embodiment of the dispenser or receptacle 14. Specifically, in the current embodiment, the chances of the drive member 22' contacting the chemical- water solution are drastically reduced. In the first embodiment, if the seal 28 leaked, the drive member 22 could potentially be ruined by contact with the chemical solution. In this embodiment, the drive member 22' is not positioned where liquids can easily contact the drive member 22' .
- the funnel 57' is supported in the housing of the dispenser 14' in a bearing type relationship.
- the funnel 57' is provided with drive connection 58'.
- the drive connection 58' is a toothed portion that engages a similarly toothed belt that is powered by a motor.
- the drive portion can be configured other ways.
- the drive portion can be given a gear tooth profile that can be driven directly by a motor or other gear train.
- the runnel can be powered by other means known and understood in the art.
- the inside of the runnel is provided with a projecting member, such as a finger or tab 59' that extends upward from the inner surface of the funnel 57'.
- a projecting member such as a finger or tab 59' that extends upward from the inner surface of the funnel 57'.
- this tab 59' extends toward and engages a portion of the closure 10' to selectively drive the closure between dispensing and non-dispensing positions.
- the tab 59' illustrated in this embodiment is just one of many ways to drive the closure 10' with the funnel 57'. It should be understood that many other means can be used to drive the closure with the funnel, such as an engagement between the periphery of the closure 10' and the funnel 57'. Further, the tab 59' from the funnel 57' could be received within a recess on the closure 10' in some embodiments.
- the funnel can be provided with a device so that the position of the funnel and the closure can be sensed or otherwise determined by the dispenser 14'.
- a magnet 61 is coupled to the funnel 57' and sensed by the dispenser 14'.
- a Hall effect sensor can be used to sense the magnet. With such a device, the dispenser can always know the rotational position of the closure and the funnel 57' and stop the funnel 57' and the closure 10 in a predetermined position after a select number of rotations.
- a magnet and Hall effect sensor are disclosed, other embodiments can employ other position sensing techniques by using optical encoders, contact sensors, as well as other known techniques.
- FIGURES 24-27 a metering and dispensing closure 1OE embodying inventive aspects is illustrated.
- This metering and dispensing closure is composed of the three basic components discussed above in the previous embodiments (i.e., a cap member 30, rotatable disk 36, and rotatable disk 43).
- this embodiment also includes additional features, such as the projecting tab 66E mentioned above to allow the closure 1OE to be driven by the funnel 57'.
- the closure also includes one or more resilient figures 68E adapted to assist with clearing out an opening in the dispensing closure 1OE.
- the closure 1OE includes a scraping member 7OE to clean and prevent dispensed chemicals from caking on the outside of the closure.
- a cap member 3OE with an upstanding wall 3 IE and a coupling means 32E, such as threads or snap fit projections for engaging complementary engagement members, such as threads on the container 12.
- a coupling means 32E such as threads or snap fit projections for engaging complementary engagement members, such as threads on the container 12.
- a first moveable member, rotor, or rotatable disk 36E coupled to the inside of the cap 30E.
- the rotatable disk 36E includes a cutaway portion 38E that allows product to be dispensed from the container 12 and into a measuring chamber 33E of the cap 3OE.
- a second movable member, rotor, or rotatable disk 43E is coupled to the outside of the cap 30E.
- the first member 36E is coupled to the second movable member 43E via a stub shaft 48E with projections 49E extending between the two members.
- the stub shaft extends through an opening 34E in the cap member 30E between the two members.
- the projections engage the other member to connect the two members, such that they rotate together.
- the opening in each disk is rotatably off-set with respect to each other. Accordingly, the contents of the container can never freely communicate with the environment outside the container.
- a projecting tab 66E extends from the outer rotatable disk 43E.
- the tab 66E extends from the disk 43E in a direction generally parallel with the axis of the disk 43E. However, in other embodiments, the tab 66E can extend in other directions.
- the tab 66E is dimensioned and configured to extend toward the funnel 57' and engage the projection or tab 59' on the funnel 57' when the closure 1OE is engaged with the dispenser 14'. As mentioned above, due to this engagement, the funnel 57' can drive the disks 43E, 36E on the closure 1OE to selectively rotate and dispense the contents of the container.
- the runnel 57' engages and drives the tab 66E on the outer disk 43E 5 which causes rotation of the outer disk 43E, and due to the connection between the inner disk 36E and the outer disk 43E, it also causes rotation of the inner disk 36E.
- the outer disk 43E includes a scraping device 7OE positioned on an edge of the opening in the disk 43E.
- the opening in the disk 43E is generally a sector shaped opening.
- One edge of the sector shaped opening is provided with a substantially concave shaped edge.
- the substantially concave shaped edge terminates in a point or an edge forming an acute angle. This edge is dimensioned and configured to contact the opening 33E in the cap 3OE when rotated. As the edge passes by the opening 33E, it scrapes any caked or otherwise stuck materials from the outer surface of the opening 33E.
- this scraping interface 7OE is provided with a generally concave shape. This shape has been shown to help prevent the scraped materials from collecting on the outer surface of the outer disk 43E.
- this scraping interface 7OE can be provided with different configurations. For example, the surface of the scraping interface 7OE can be substantially flat.
- the shape of the dosing hole 33E has been altered.
- the dosing hole 33E through the cap member 30E is substantially circular.
- the dosing hole 33E is more rectangular. More specifically, the shape is a truncated sector, a curved rectangle, or curved trapezoid. In such embodiments, it has been found that some powdered materials are more likely to be encrusted on the closure 10 with this shape than with the circular shape. This may be due to the corners in this configuration, which tend to provide a location for materials to encrust and build-up.
- the closure 1OE can also be provided with elastic fingers or flippers 68E configured and positioned to sweep the contents out of the dosing hole 33E in the cap 30E.
- the fingers 68E extend from the inner disk 36E toward the inner surface of the cap member 30E. Due to this configuration and the tolerances between the cap and the inner disk, the fingers 68E are generally biased or bent-over by the cap 30E at most times.
- the elastic forces of the fingers 68E cause them to bias back into an extended, substantially non-bent (or less bent position) position, which allows the fingers 68E to extend into the dosing hole 33E.
- the fingers sweep, push, or otherwise provide a force generally sufficient to clear most of the powder from the hole 33E.
- the fingers 68E are positioned on the inner disk 36E at an appropriate position so that they align with the hole 33E in the cap 3OE when the outer disk 43 moves such that the hole 33E is in an open position.
- the fingers 68E extend into the hole 33E in the cap 30E when the inner disk 36E is in a closed position relative to the hole 33E and the outer disk 43E is in an open position with respect to the hole.
- the fingers 68E are located within a recess 72 of the inner disk 36E. This recess 72 generally extends from inner disk 36E away from the cap member 30E. With such a configuration, the fingers 68E are provide with some clearance to bend (when not aligned with the hole 33E), which can reduce the friction between the cap 3OE and inner disk 36E.
- closure 1OE or cap 30E of this embodiment is provided with a curved or generally funnel-shaped inner surface.
- the shape of this surface provides an advantage of funneling the contents of the container to the opening in the closure. As such, the contents of a container having this shape to the cap may dispense better.
- FIGURES 13-27 A better understanding of the metering and dispensing device illustrated in FIGURES 13-27 will be had by a description of its operation.
- the dispensing closure 1 OE coupled to container 12' filled with a powdered material.
- the dispensing closure 1OE and the container are supported in the dispensing receptacle 14' as shown in FIGURE 13.
- the drive member 22' is actuated to cause the funnel 57' to rotate.
- Rotation of the funnel 57' causes the disks 36E, 43E on the closure 1OE to rotate.
- engagement between a projection 59' on the funnel 57' and a projection on the outer disk 43E of the closure 1OE cause the transfer of power from the funnel 57' to the closure 1OE.
- Actuation of the outer disk 43E causes the inner disk 36E to rotate as described above.
- FIGURES 3 and 3A illustrate a different embodiment, some of the main principles of operation are consistent better these two embodiments. Accordingly, earlier embodiments may be referenced to indicate relative positions of the disks with respect to each other.
- the inner disk 36E is positioned to allow the contents of the container 12 to communicate with the opening 33E in the cap member 30E (open position) and the outer disk 43E is positioned to block the flow of materials out of the opening 33E in the cap member 30E (closed position).
- the granular or powdered materials within the container 12 flow into the opening 33E in the cap 3OE. Since the outer disk 43E blocks the flow of materials out of the opening 33E (or measuring chamber) in the cap 30E, a specific known amount of material can flow into and fill the opening 33E.
- the inner and outer disks 36E and 43E are rotated through a position illustrated in FIGURES 4 and 4A to a position as illustrated in FIGURES 5 and 5A.
- the inner disk 36 blocks the opening 33 in the cap member 30 and the outer disk 43 is positioned to allow materials to flow out of the opening 33 in the cap 30. Accordingly, the materials within the opening 33 can fall out of the opening 33 in the cap 30.
- the fingers or flickers 68E on the inner disk substantially align with and resiliently extend from a biased or bent over position to a substantially extended position while the outer disk 43E allows the opening 33E to be open. The extension of these fingers 68R help to remove most additional materials that may be building up or caked within the opening 33E.
- the disks preferably continue to rotate to a position wherein the outer disk 43E closes or blocks the opening 33E in the cap 30E. This will help prevent moisture from entering the opening 33E in the closure 1OE.
- the disks 36E, 43E on the closure 1OE stop in a position wherein both the inner disk 36E and the outer disk 43E are positioned to block or close the opening 33E. While moving to one of these preferred positions, the scraping device 7OE on the outer disk 43E passes over the outer rim or surface of the opening 33E in the cap 3OE and engages stuck, caked, or encrusted materials on the outer surface of the opening 33E to remove those materials.
- the materials fall into the funnel 57' and are flushed from the funnel 57' by water entering the funnel 57'. Rotation of the funnel 57' helps assure that the water flushes all materials out of the funnel 57'. Once the chemicals are mixed with the water, they can be dispensed via the outlet 20'.
- a metering and dispensing closure 1OF is illustrated.
- This metering and dispensing closure 1OF is configured and dimension to operate with the dispenser or receptacle 14' illustrated in FIGURE 13.
- This metering and dispensing closure 1OF is composed of the three basic components discussed above in the previous embodiments (i.e., a cap member 30, rotatable disk 36, and rotatable disk 43).
- this embodiment also includes many of the additional features of the embodiment illustrated in FIGURES 25-27, such as the projecting tab 66F mentioned above to allow the closure 1OF to be driven by the funnel 57,' the resilient figures 68F adapted to assist with clearing out an opening 33F in the dispensing closure 30F, the scraping member 7OF on the outer disk 43F, and the generally concave shape of the closure 1OF relative to the container.
- the projecting tab 66F mentioned above to allow the closure 1OF to be driven by the funnel 57
- the resilient figures 68F adapted to assist with clearing out an opening 33F in the dispensing closure 30F, the scraping member 7OF on the outer disk 43F, and the generally concave shape of the closure 1OF relative to the container.
- the shape of the opening 33F in the cap member 3OF is substantially circular. However, in this embodiment, the dosing hole 33F is more rectangular. More specifically, the shape is a truncated sector, a curved rectangle, or a curved trapezoid. Due to this configuration, the recess 72F housing the resilient fingers 68F also has a similar shape.
- this embodiment is provided with a hook-like member 76F that extends from the inner disk 36F.
- This hook-like member 76F stirs, agitates, and/or drives dispensable materials within the container toward the opening 33F in the closure 1OF. Accordingly, with such a feature, the container may be better depleted relative to the previous embodiments.
- the hook-like member 76F generally extends along and adjacent the inner surface of the cap 30F.
- the hook-like member 76F is also generally curved to follow the generally concave profile of the cap 3OF.
- FIGURES 31-36 illustrate another closure 1OG adapted to be used with the dispensing assembly shown in FIGURE 13.
- This closure 1OG has many features in common with the previous embodiments, but operates under a slightly different principle than the previous embodiments.
- the previous embodiments used two moving members (e.g., disks 36, 43) to selectively block and unblock a static, non- moving aperture or measuring chamber 33 in the cap 30.
- This embodiment constructed slightly different than the previous embodiments to incorporate a moving measuring chamber.
- this embodiment includes a cap member 30G and two moveable members 36G, 43 G to meter the dispensing of contents from a container 12' coupled to the closure 1OG.
- the closure 1OG of this embodiment arranges the moveable members 36G, 43 G in a manner somewhat different from the previous embodiments.
- the cap 3OG generally has many features in common with the previous embodiments, such as a generally concave shape to funnel materials to an aperture 33G in the cap 3OG and walls that engage a container. Accordingly, these features will not be discussed in depth.
- this closure 1OG includes a cap member 3OG, an outer rotor or rotating disk 43G, and an inner rotor or rotating disk 36G.
- the closure 1OG also includes a baffle plate 80G and a rotating hook-like member or arm 76G.
- the cap member 30G has an inner surface relative to the container that it is adapted to be coupled to and an outer surface.
- the inner surface is generally concave shaped to help direct materials within the container to a dispensing position and to better deplete the bottle.
- the outer surface of the cap 3OG that is positioned adjacent the outer rotor 43 G is generally flat. This generally flattened surface has been found to prevent encrustation or other build-up of dispensed product.
- the cap member 3OG has two apertures in this generally flattened surface.
- One aperture 34G is substantially centered in the cap 3OG to receive a shaft.
- the other aperture 33G is generally off-center. This second aperture 33G defines an opening in the cap member wherein materials contained within the container 12 can be dispensed.
- the outer rotor 43 G is positioned on the outside surface of the cap 30G.
- the outer rotor 43G has a shaft 48G that extends through the cap 3OG to define a pivot for the rotor 43G.
- the outer rotor 43G has a generally sector-like shape configured and dimensioned to selectively block the opening 33G in the cap 3OG. Rotation of the outer rotor 43G causes the rotor to selectively block and unblock the opening 33G in the cap 3OG.
- the outer rotor 43 G can be driven many ways, as described above. However, in the illustrated embodiment, a projecting member 66G, such as an arm or tab, extends from the outer rotor in a generally radial direction.
- This projecting member 66G is engaged by and driven by the projection drive member 59' on the funnel 57', as described above.
- the outer rotor 43E also has a scraping member 7OG, as described above, which engages the substantially flat outer surface of the cap 30G to remove caked, encrusted, or otherwise stuck dispensed materials.
- the inner rotor 36G is positioned on the inside of the cap 3OG and rests with a recess 82G of the cap (FIGURE 36). Like the previous embodiment, the inner rotor 36G is coupled to the outer rotor 43G such that rotation of one rotor causes rotation of the other rotor.
- the inner rotor 36G is coupled to a shaft 48G extending from the outer rotor 43G.
- the inner rotor 36G has a generally circular body and an aperture 38G extending through the body.
- a wall 39G extends in a generally axial direction adjacent this aperture to at least partially define a metering chamber.
- this metering chamber rotates with the inner rotor 36G to deliver a predetermined quantity of product from within the container 12 to the aperture 33G in the cap 30G.
- This wall 39G positioned adjacent the aperture 38G acts as a ram to drive the predetermined quantity of material to a dispensing position.
- this wall 39G or additional walls extending from the inner rotor 36G can have an interfering fit against the cap 3OG so that the wall 39G may be slightly flexed when not aligned with the opening 33G in the cap 3OG.
- the wall 39G passed over the opening 33G or other slightly projecting member on the inner surface of the cap 3OG, it can momentarily get caught against the opening 33G or projecting member.
- the wall 39G flexes sufficiently due to continued rotation of the rotor 36G, the wall 39Gwill be resiliently biased back to a less flexed position. This biasing will cause sufficient vibration to release stuck, caked, or compacted materials within the opening or measuring chamber.
- the closure includes a baffle plate 80G.
- the baffle plate 80G is coupled to the cap 30G in a non- rotatable manner.
- the baffle plate 80G is positioned adjacent the inner rotor 36G.
- the baffle plate 8OG at least partially forms a recess 82G within the cap 30G for housing the inner rotor 36G.
- the baffle plate 80G has an aperture 84G to allow materials within the container 12 to move passed the baffle plate 8OG and enter the measuring chamber 38G of the second rotor 36G, when the second rotor 36G is properly aligned with aperture 84G in the baffle plate 8OG.
- the closure 1OG also has a hook-like member or arm 76G that rotates adjacent the baffle plate 80G.
- This hook-like member 76G helps to deliver materials within the container to the opening 84G in the baffle plate 8OG.
- the rotors 36G, 43G are rotated to selectively dispense product from the container.
- the opening 30G in the inner rotor 36G will be placed in communication with the contents of the container 12. Specifically, this occurs when the opening 38G in the inner rotor 36G at least partially aligns with the opening 84G of the baffle plate 80G.
- the opening 38G in the inner rotor 36G will fill with a predetermined amount of material.
- the opening 38G in the inner rotor 36G is no longer in communication with the opening 84G in the baffle plate 80G.
- the dispensing closure of this invention has been described in conjunction with particular configurations of receptacles or dispensing assemblies. It should be understood that any type of receptacle or dispensing assembly can operate in conjunction with this dispensing closure. They do not necessary have to have a receptacle dispensing assembly that contains water. For example, they could be utilized in a receptacle and supported therein where the powder material would drop into another container having a liquid predisposed therein. Neither is it necessary that the dispensing closure be employed in conjunction with a receptacle or dispensing assembly employed with water. Other liquids such as water miscible and immiscible solvents including water and ether could be employed.
- the dispensing closures illustrated herein can be utilized with other containers.
- the container may have two or more chambers containing separate chemicals within each chamber.
- the chambers can be utilized to keep two or more chemicals separate from each other until dispensed.
- the closure could be provided with an opening communicating with each chamber. One complete rotation could then dispense the materials contained within each chamber either simultaneously or sequentially depending upon the configuration of the closure.
- one particular advantage of the illustrated closures is that they provide greater flexibility with respect to the formulations dispensed for cleaning applications.
- detergents the most commonly fed powders
- the caustic (typically NAOH or KOH) level needed to be kept below about 40% to prevent the possibility of steam generation within the container.
- NAOH or KOH the caustic level needed to be kept below about 40% to prevent the possibility of steam generation within the container.
- this limitation is substantially removed due to the inability of moisture to enter the container because of the construction of the closure.
- more powerful detergent powders can be formulated with perhaps up to 70% caustic concentrations without the threat of exothermic heat generation. This would represent a 40% to 50% increase in "power" in a single container.
- the moveable members, rotors, or disks described above can move in manners other than those described above.
- the moveable members can also include sliding members that move in a linear, curvilinear, or other path between open and closed positions to selectively block the aperture in the cap.
- various alternatives to the certain features and elements of the present invention are described with reference to specific embodiments of the present invention. With the exception of features, elements, and manners of operation that are mutually exclusive of or are inconsistent with each embodiment described above, it should be noted that the alternative features, elements, and manners of operation described with reference to one particular embodiment are applicable to the other embodiments.
